The laser engraving machine equipment is precise, so it is necessary to pay attention to the protection beside the operation, and the usual attention to maintenance and protection can increase the service life of the equipment, save costs, and create greater benefits.

1、 Water replacement and water tank cleaning

Attention: Make sure that the laser tube is filled with circulating water before the machine works.

The quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35 ℃. If the temperature exceeds 35 ℃, it is necessary to replace the circulating water, or add ice to the water to reduce the water temperature (the user is recommended to select a cooler or use two water tanks).

Clean the water tank: first, close the power supply, unplug the water inlet pipe, let the water in the laser pipe flow into the water tank, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, stab the water pipe connecting the water pump into the water inlet, and tidy the joints. Turn on the water pump separately and run it for 2-3 minutes (fill the laser tube with circulating water).

2、 Fan cleaning

The long-term use of the fan will cause a lot of solid dust to accumulate inside the fan, make the fan produce a lot of noise, and is not conducive to exhaust and deodorization. When there is a lack of fan suction and the smoke exhaust is not smooth, the power supply shall be closed first, the inlet and outlet air ducts on the fan shall be removed, the dust inside shall be removed, and then the fan shall be inverted, and the fan blade inside shall be pulled until it is clean, and then the fan shall be installed properly.

3、 Cleaning of lens

There are three reflectors and one focusing mirror on the laser engraving machine (the No. 1 reflector is located at the emission exit of the laser tube, which is also the upper left corner of the machine, the No. 2 reflector is located at the left end of the beam, the No. 3 reflector is located at the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable mirror tube at the lower part of the laser head). The laser is reflected and concentrated through these lenses and then emitted from the laser hair. The lens is easily stained with dust or other pollutants, resulting in laser loss or lens damage. The No. 1 and No. 2 lenses do not need to be removed when cleaning. Just carefully scrub the lens paper dipped with cleaning solution along the center of the lens to the edge. The No. 3 lens and the focusing lens need to be taken out of the frame, scrubbed in the same way, and then put back in the same way after scrubbing.

Attention: 1. The lens should be cleaned quietly, and the external coating should not be damaged; 2. Handle gently during scrubbing to avoid falling; 3. Please keep the concave side downward when assembling the mirror device.
